Ragequit the game out of frustration, but aim to try it again sometime this week.
What I did notice though was that almost every, if not all, goals came from set pieces. At least three goals came from corners, and one from a free kick situation just outside the box. My players lost the air battle, which sounds unreasonable seeing as Milan today has Romagnoli, Musacchio and Caldera, neither which are weak in the air. Romagnoli is very much suited as a cover defender, as well.
As for the other players, very likely that they werent up to par according to your archetypes. Rodriguez isnt a finisher, but he's solid in terms of speed and crossing. Calabria is competent as a CWB, although he lacks a bit of offensive power.
I suppose the midfield trio could've been the weak link in this, alongside with the treq, Calhanoglu. Montolivo is a good DLP (less competent than Biglia, but Biglia is the anti-thesis to your idea of a DLP) but lack some of the PPMs listed, Kessie and Bakayoko, although good on paper, didnt do much. Higuain was pointless, despite his qualities.
I like the idea and the formation that you have concocted, but have you noticed if the tactic is especially susceptible to goals from set pieces?
